Popular enterprise architecture frameworks like TOGAF and ArchiMate each provide meta models, but none are broad enough to fully support strategic planning, contextual analysis, and business architecture alongside risk, change, and programme management in an integrated way. This paper describes the development of HAL2023 — an updated version of the Inspired Holistic Architecture Language — synthesising concepts from TOGAF 10, ArchiMate 3.2, BizBOK 11, SABSA, MEMO, and the Inspired consulting practice into a single, coherent meta model validated across multiple industries. It addresses not only what the model contains, but how it can be practically applied without overwhelming practitioners.
Enhancing Enterprise Architecture Models with Cost, Quality and Risk Dimensions
Enterprise architecture models are typically rich in structural detail but silent on cost, quality, and risk — the very dimensions that drive executive decision-making. This 2003 presentation by Graham McLeod, delivered at the University of Cape Town, explores how EA models can be extended with these critical dimensions using a knowledge repository approach, enabling architects and business managers to assess current and future scenarios with a fuller picture of the implications of their decisions.
